SINK.

SPECIFICATION forming part of Letters Patent No. 595,544., dated December 14, 1897.

Application tiled April 14, 1897.

.To @ZZ whom it may concern,.-

Be it known that'I, WILLIAM LOVE, a citizen of the United States, residing at Bryn Mawr, in the county of Montgomery and State of Pennsylvania, have invented a certain new and useful Improvement in Sinks, of which the following is a specification.

My invention relates to a new and useful improvement in sinks, and has for its object to cast in a single piece a sink and the backing therefor and to provide means for the ready cleaning of both the waste-pipeand overflow and also to overcome the disadvantage which has heretofore existed in devices of this description from osets and projections which afford a shelter for various kinds of insects, such as roaches; and a further object of my improvement is to so cast the sink and back as to preclude the possibility of the the outside of the sink, and .incidentally my improvement facilitates its securement in place, as well as the removal of any portion of the connecting-pipe for repair or renewal.

With these ends in View this invention consists in the details of construction and combination of elements hereinafter set forth and then specifically designated by the claims. In order that those skilled in the art to which this invention appertains may understruction and operation will now be described in detail, referring to the accompanying drawings, forming a part of this speciiication, in which- Figure lis a perspective View of myimprovement when in place; Fig. 2, a vertical section thereof; Fig. 3, an enlarged cross section showing the arrangement of the waste-pipe and overflow; Fig. 4, an enlarged section of the coupling, and Fig. 5 a front view of the three-way coupling.

In carrying out my invention as here embodied I form the sink proper, A, with the back B by casting, and I prefer, that this back shall stand at right angles to the body of the sink and have no projection upon its rear surface in order that it may be secured to a wall or wainscoting and when so secured will serve to support the sink with or without the use of legs or brackets.

In casting the back has formed thereon Serial No. 632,177. (No model.)

` casing-pipes C to receive the water-pipes D,

and these casin gs are cut away from the back at the top, thereby producing a shoulder, and couplings E, having iiat rear walls E2, are fitted over the upper ends of said casings and have downwardly projecting iianges E3 formed thereon, which inclose the tops of the casings. The upper ends of said casings abut shoulders formed along the bosses at the front of the couplings. These couplings are threeway, the upper and lower openings to which are threaded for the reception of the Waterpipes, or in case a pipe does not lead from the upper portion ofv the coupling then the opening therein may be closed by a fancy screwplug E. The Water-pipes D are passed within the casingpipes C from their upper open ends prior to placing the couplings E in place, and afterward these pipes are threaded into the lower openings in the couplings, thereby not only securing the couplings in place, but also connecting the pipes thereto. The horizontal openings in the couplings are for the reception of the threaded shanks of the spigots F, and when a hot-Water apparatus is i used instead of the plugs E the pipes which lead vto and from the boiler are threaded in the upper openings of the couplings. By this arrangement it will be seen that all parts of the piping and joints therefor are so completely closed and surrounded as to prevent access thereto of insects or the accumulation of dirt, which is of considerable importance fromv a sanitary point of View.

The waste-pipe G is secured to the trap H by being threaded in the lower end thereof, and this trap is preferably cast with the sink, in order that there may be no holes necessary for the passage of bolts, thus avoiding an occasion for leakage, which often occurs in sinks as now constructed. Within the trap is formed an annular shoulder, upon which the screen I rests, and this screen is so arranged that it may be readily removed from the washer for cleaning purposes and in order that the pipe of a force-pump may be placed within the waste-pipe whenoccasion requires.

The overflow-pipe .I is cast with the body of the sink and leads downward and inward and enters the trap, while a clean-out L is formed therein having internal threads for the reception of the threaded plug M, which IOO may be readily removed and by means of which a. Wire or other implement may he passed into the pipe K in either direction for cleaning the same.

In order that free access may be had to the overflow-outlet and the pipe connected therewith, the screen O is hinged over said outlet and adapted to be swung upward out 0f the way when access is to be had to the overflow.

In practice I prefer that a plug P may be adapted for iittin g Within the Waste-pipe outlet in order that the sink may be used instead of the usual tin pan for dish-Washing, since when this plug is in place Water may be accumulated Within the sink to the level of the overflow. When the supply-pipes are to be connected with a hot-Water boiler, either or both of the plugs E may be removed from the housings and the pipes leading to and from the boiler connected at this point With the supply-pipes and valves placed Within said pipes, so as to control the flow of the hot Water throughout the house from the sink, which will often save annoyance and damage by being able to shut olf the Water should a leak occur without the loss of time necessary to reach the main stop-valve.

In the formation of my improved sink I prefer that the bottom thereof shall slope in all directions toward the ivaste-pipe and that the corners thereof shall all be so rounded as t0 cause the free flowing o of Water and grease, thereby greatly facilitating the cleaning of the sink and improving its sanitary condition.

An important feature of my improvement is that no woodwork is needed for placing the sink, and as this woodwork invariably be comes fouled by constant soaking in of water, grease, and impurities it follows that the use of such wood is objectionable, and When dispensed with the sink is rendered more cleanly and desirable.

My improved sink is especially adapted for use in pantries and the like, since the pipes may be readily connected therewith and the sink held in place Without Woodwork or brackets, and when so arranged accumulation of dirt or the harboring of insects is entirely prevented.

Having thus fully described my invention, what I claim as new and useful is l. A sink cast in a single piece consisting of bottom, front and side Walls, and a back extending upwardly at right angles to the bottom and above the other Walls, vertical casings formed on the back to inclose the water-pipes, said casings being cut away from the back near their tops, couplings having flat rear walls, each also having a vertical passage therethrough with a second passage leading from the iirst-named passage, the ends of the passages being screw-threaded, a downwardly-projecting flange formed on the coupling and inclosing the top of the casing, the top of the casing tting against a shoulder in the coupling, plugs threaded in the upper ends of the vertical passages, and means for securing the couplings to the back of the sink, as and for the purpose described.

2. In a device of the character described, a sink body and back formed together, said back having Ways formed therein for inolosing Water-supply pipes, the wall at the top of the Ways being recessed or cut away to form a shoulder, couplings having flat rear Walls tting in the recess, said rear walls of the coupling being of greater length than the front walls of the coupling, a shoulder formed on the boss at the front of the coupling fitting against the end of the casing, as and for the purpose set forth.

In testimony whereof I have hereunto affixed my signature in the presence of two subscribing witnesses.

VILLIAM LOVE.
